C. RUPF' METAL WINDOW FRAME AND SASH F'lfed June l1, 1924 2 Sheets-Sheet 2 MWF/WW: wmf.; A?? y integrally united, conveniently by welding, to the top and bottom rails 5 and 6. Each of said sash side members 4 has two lugs 9 and 1() punched to project therefrom, transversely to the plane of the sash, i. e., 1n substantially horizontal planes, but in unitary relation with said plates. A Each of said lugs 10 is provided with means forattaching thereto flexible connectors for sash weights, including a circular punched hole 11 through the lug, as indicated in Fig. lV, with respective chain links 12 extending therein as indicated in Fig. V. However, it is unnecessary to provide such openings 11 in the lugs 9 which merely serve as guides for the sash in connection with the window jambs.

Referring to Fig. IV, each of the sash plates 4, 5 and 6 is offset to form two steps 14 and 15, in planes parallel with the plane of the glass 16. As shown in Fig. V, the step 14 receives the edge of the glass 16 and the plastic material 17 for securing said glass in the sash, and said glass and such material are retained in the sash by the vertical face plates 18 shown in Fig. V, in conjunction with the other face plates shown in Fig. VI, viz, the upper face plate 2O of the upper sash; the lower face plate 21 of the upper sash; the upperface plate 22 of the lower sash; and the lower face plate 23 of the lower sash. It may be observed that the positions of all of said face plates are determined by the respective shoulders 24 on said sash frame plates 4, 5 and 6, and that said face plates are thus received and held within the thickness of the sash., conveniently by flat headed screws connecting them with the respective sash frame plates. As shown in Fig. VI, said face plate 21.011 the rail 6 of the upper sash, is conveniently formed in unitary relation with the channel 25 which cooperates with the flange 26 of the channel bar 27 on the rail 5 of the lower sash 2, to form a substantially wind tight joint at such meeting rails of said sashes, when the latter are in the norma-1 closed position indicated in Figs. I and VI.

As indicated in Fig. V, the inner vertical edges of said panes of glass 16 are secured in the plasticjmaterial 17 in the muntin bars 8 and retained by the face plates 28 which are conveniently detachably 4connected with said bars 8 by the screws 29. I

The transversely extending flanges 31 on said sash lates 4 extend through respective slots in the cheek of the hollow jamb 32 whichcheek, as shown in Fig. V, includes the central vertical parting bar channel 33, the inner weathering bar 34 and the outer weathering bar 35,l all rigidly connected with said jamb 32. 'As shown in Fig. V,

said jamb 32'isl formed' of a single piece of pressed sheet metal having its inner edge doubled and offset as indicated at 37 to form a seat for said cheek members 33 and Lis/faves 34 which are rigidly connected therewith, conveniently by bolts 38. Said jamb 32 is folded at its outer corner to form the anchor flange 39 which is embedded in the cement 40, or otherwise secured between the wall members 41 and 42 which are preferable masonry. The outer edge of said jamb 32 is folded to form the seat 45 to which said outer weathering bar 35 is conveniently rigidly connected by the bolts 46. Said jamb 32 is also folded to form the channel 47 for resilient engagement with the flange 48 on said parting bar channel 33 to form a wind tight joint therewith without riveting. It is to be understood that the flange 48 of said parting bar channel 33 is inserted in said jamb channel 47, in resilient engagement therewith, before said member 33 is rigidly connected to the jamb by said bolts 38, thus lessening the labor and the cost of assembling the structure.

It may be observed that the construction above described is such as to form respective substantially wind tight chambers -50 and 51 in the cheek of each jamb to receive the sash flanges 31 and the lugs 9 and 10 projecting therefrom.

Referring to Figs. V and VI, it is to be understood that chains or other flexible connectors 53 extend from said links 12 over respective sheaves 54 to the respective sash weights 55 which are free to rise and fall in the hollow of the respective jambs 32 but are separated by parting strips 56. As shown in Fig. VI, said sheaves 54 are conveniently journaled in franies 57 which are riveted in the upper portions of said jambs or otherwise rigldly connected therewith.

As shown in Fig. VI, the head section of the window frame includes two members 58 and 59 of pressed sheet metal. The main member 58 has the inwardly extending angle channel 60 in its lower portion, inclined to the plane of the sash, to receive and engage the upwardly extending flange 61 on the top rail 5 of the upper sash in substantially wind tight relation. 58 is folded at lts upper front edge to form an anchor flange 62 extending between the lintel members 63 and 64, the former being adapted to hold the portion of the wall 65.

Said head member 58 has'at its upper edges, fianges 66 -and 67 forming seats for said member 59, whichis a cap plate extending beneath said lintel member 64 and another lintel member 68 and may be sealed inconnection therewith by the plastic material 69 which extends in the interstices between the window frame and said wall members. Said head section is also provided with the weathering bar 71, which is similar in cross section to the bar 35shown in Fig. V and is conveniently rigidly connected with said head member 58 by the bolts 7 2.

As shown in Fig. VI, the sillsection of llO Said member lfl Luarca the window frame is formed of the hollow meta-l channel 'Pl having inwardly turned flanges and 76 respectively at its outer and inner bottom edges, which rest upon the wall members 77 and 78 to which said sill member is conveniently connected by the plastic material 80. Said sill member 74 has the shoulder 81 which is slightly inclined outward for Contact with the lower flange 82 on the bottom rail 6 of the lower sash, and said sill member 7a has the second shoulder 83 similarly inclined for contact with the rail 85 which is rigidly connected with said lower sash member. It is to be understood that the arrangement above described is such as to make a substantially tight joint between the sill and the lower sash, when the latter is closed in the position shown in Fig. Vl,

In order to facilitate manipulation of said sashes l ,and 2, li find it convenient' to provide them withl respective handles 87 andh Sti-which are rigidly connected therewit lt is to be particularly noted that the lateral play of said sashes is limitedby the ledges 89 and 90 which are `offset so as'to limit such movement by contact with the cheek members of the respective jambs 32.' That is to say, the upper sash l has the ledge 89 adapted to encounter the weathering strip 35 of said jamb cheek, and the sash-2 has the shoulder 90 adapted to en? counter the cheek member 33. Although as shown in Fig. V, said lugs 9 and 10 extend in such position as to appear to limit the movement oi the sash outward with respect to said jainb cheekl members 34 and 35; they'` do not present sudicient surface to withstand the wear incident to the opening and closing movement of said sash, whereas, the ledges 89 and 90 aforesaid extend the full height of the respective sashes and thus afford ample wearing surface.

Although l have found it convenientto mount the sash shown in Fig. l in window frames of the specific construct-ion shown in Figs.. V and Vil, it is to be understood that ll do not desire to limit myself to such embodiment thereof. Moreover, the window frame construction shown in Figs. V and V has advantages which are independent of the specific details of construction of the sash above described.

Therefore, l do not desire to limit myself to the precise.l details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as delined in the appended claims.
